Vitalik Buterin has proposed a fundamental redesign of how DeFi lending works, pitching an options-based model that would eliminate forced liquidations entirely. The Ethereum co-founder published the theoretical framework on June 1, 2026, arguing that options contracts could replace the collateralized debt positions that currently underpin billions of dollars in DeFi lending.
What Vitalik Is Actually Proposing
In a post titled “Building index-tracking assets on top of options instead of debt” on the Ethereum Research forum, Buterin posed a direct challenge to the current DeFi architecture: “What if we use options as the base of DeFi, instead of CDPs and liquidations?”
The proposal replaces collateralized debt positions, the mechanism behind protocols like MakerDAO, Aave, and Compound, with options contracts tied to asset price indices. Instead of borrowers posting collateral that can be seized when prices drop, Buterin’s model splits deposited ETH into two components, labeled P and N, that always sum to the original amount deposited.
Payouts under this system are determined at maturity through oracle settlement, not by real-time liquidation triggers. This is the core innovation: no position can be forcibly closed mid-contract because of a sudden price move.
The instruments track a price index Buterin calls “T,” which could represent USD/ETH, CPI-based measures, or other benchmarks. Buterin noted that he would feel much safer holding algorithmic stablecoins built on an options-based structure than one dependent on real-time oracle feeds vulnerable to manipulation.
A key design choice is the use of “slow oracles” similar to those found in prediction markets. These reduce the risk of flash-loan manipulation, a persistent vulnerability in current DeFi systems that rely on real-time price feeds to trigger liquidations.
Why Liquidations Remain DeFi’s Recurring Crisis
The proposal lands during a period of genuine market stress. The Crypto Fear & Greed Index sits at 29, firmly in “Fear” territory, the kind of environment where liquidation cascades pose real risk to DeFi borrowers.

Current CDP-based lending works on a simple but brutal mechanism: borrowers deposit collateral (typically ETH or other volatile assets), borrow against it, and face automatic liquidation if the collateral value drops below a set threshold. Liquidation penalties, often 5-13% of the position, compound losses for borrowers while creating profitable opportunities for liquidation bots.
DeFi has seen devastating cascades during prior market crashes. The March 2020 “Black Thursday” event saw MakerDAO liquidations spiral as ETH prices collapsed, with some vaults liquidated at near-zero prices due to network congestion. The May 2021 crash and the Terra/LUNA collapse in 2022 triggered similar waves across Aave, Compound, and other lending protocols.
ETH itself has declined -13.64% over the past 30 days, trading at $1,995.82 with a market cap of $241.45 billion. That kind of sustained drawdown is precisely what triggers cascading liquidations in CDP-based systems.

Some protocols have attempted partial fixes. Curve’s crvUSD introduced “soft liquidations” through its LLAMMA mechanism, gradually converting collateral rather than triggering abrupt full liquidations. But even soft liquidation models still depend on real-time oracle feeds and can still force position closures during extreme volatility.
What This Means for Ethereum’s DeFi Ecosystem
Buterin’s proposal is explicitly theoretical. It has not been submitted as a formal Ethereum Improvement Proposal, and no live protocol has implemented the design. This is a conceptual discussion post, not a development roadmap.
The practical hurdles are significant. Buterin acknowledged that the system requires regular portfolio rebalancing, with roughly 1-4% annual drift considered acceptable. Rebalancing slippage has been flagged as a “significant practical challenge,” particularly during volatile markets when slippage costs are highest.
On-chain options pricing presents another obstacle. Current DeFi options protocols like Lyra and Dopex handle relatively small volumes compared to spot and perpetual markets. Scaling options infrastructure to support a lending layer that could replace CDP-based systems worth tens of billions in TVL would require substantial protocol-level development.
The oracle design, while innovative, also introduces tradeoffs. Slow oracles reduce manipulation risk but create lag between market prices and settlement values. For users seeking stablecoin-like instruments, that lag could produce temporary depegs that erode confidence, a concern amplified by the ongoing evolution of exchange infrastructure and user expectations for real-time accuracy.
Still, the direction aligns with a broader trend in DeFi research. Multiple teams have been exploring alternatives to abrupt liquidation mechanics, and Buterin’s involvement raises the profile of this design space considerably. His track record of influencing Ethereum’s development trajectory, from the Merge to account abstraction, means protocol teams are likely to explore variations on the concept. The growing interest in cross-border crypto rails, as seen with SBI Remit’s XRP transfer milestones, underscores how quickly institutional infrastructure can adopt new blockchain paradigms once proven viable.
For DeFi users navigating current market conditions, where technical indicators are flashing risk signals across multiple assets, the proposal highlights a structural vulnerability that exists regardless of which token or protocol a borrower uses. Whether options-based lending can move from theory to production remains an open question, but the problem it targets is one the ecosystem experiences in real time with every major drawdown.
The immediate next step to watch is whether any established DeFi protocol teams or independent developers begin building proof-of-concept implementations based on Buterin’s framework. Community response on the Ethereum Research forum and from teams behind existing lending protocols will signal whether this concept has a path toward adoption.
